Description

Technical Field

[0001] This invention relates to the field of desulfurization and denitrification technology, specifically a turbocharged negative pressure water absorption desulfurization and denitrification equipment. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. Flue gas denitrification technologies mainly include dry methods (selective catalytic reduction (CCR) and selective non-catalytic reduction (SNR)) and wet methods. Compared to wet methods, dry methods have the following main advantages: lower initial investment, simpler equipment and processes, higher NOx removal efficiency, no wastewater or waste treatment, and less likelihood of secondary pollution.

[0003] The turbocharged negative pressure water absorption desulfurization and denitrification equipment disclosed in Publication No. CN 112023677 B includes a turbocharger comprising: an intake pipe, a turbine tube, and a turbine body; the intake pipe and turbine tube are interconnected, the intake pipe is connected to the air inlet of the desulfurization and denitrification cylinder, the air outlet of the turbine tube is connected to the negative pressure atomizing cylinder, and the turbine body is housed within the turbine tube; wherein, an exhaust fan is driven and connected to the turbine body via a rotating shaft; the negative pressure atomizing cylinder also includes a negative pressure water suction pipe. This turbocharged negative pressure water absorption desulfurization and denitrification equipment can ensure that the flow rate of the industrial waste gas used as atomization power meets the atomization requirements.

[0004] This turbocharged negative pressure water absorption desulfurization and denitrification equipment can ensure that the flow rate of the industrial waste gas used as atomization power meets the atomization requirements, thus ensuring that the industrial waste gas is desulfurized and denitrified more stably. However, the device does not have a filtration mechanism for the particulate matter inside the factory waste gas, which causes the particulate matter inside the industrial waste gas to remain inside the denitrification cylinder, making it inconvenient to use. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a turbocharged negative pressure water absorption desulfurization and denitrification device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a turbocharged negative pressure water absorption desulfurization and denitrification device, comprising a denitrification cylinder, a support plate fixedly connected to the left side of the denitrification cylinder, a fixing block fixedly connected to the top of the support plate, a filter mechanism fixedly connected inside the fixing block, a cleaning mechanism fixedly connected to the bottom of the fixing block, a transmission mechanism fixedly connected inside the denitrification cylinder, and a chemical inlet pipe fixedly connected to the front of the denitrification cylinder. The cleaning mechanism includes a motor, which is fixedly connected to the top of the support plate. A worm gear is fixedly connected to the back end of the motor. A transmission worm wheel meshes with the bottom of the worm gear. A rotating rod is fixedly connected inside the transmission worm wheel. Arc-shaped plates are fixedly connected to the left and right sides of the rotating rod. The arc-shaped plates are fixedly connected to the top of the support plate. An air inlet pipe is fixedly connected to the left side of the fixing block.

[0007] According to the above technical solution, a gear is fixedly connected to the side of the rotating rod away from the transmission worm gear. A rack plate meshes with the top of the gear. A limit rod is slidably connected inside the rack plate. A short plate is fixedly connected to the front and back ends of the limit rod. The short plate is fixedly connected to the top of the support plate. When the worm drives the transmission worm gear to rotate, the transmission worm gear can drive the gear to rotate through the rotating rod. This allows the gear to drive the moving plate through the rack plate and the linkage plate to move. The moving plate can then clean the filter plate with a cleaning brush, making the filter plate less prone to clogging.

[0008] According to the above technical solution, a linkage plate is fixedly connected to the left side of the rack plate, a movable plate is fixedly connected to the left side of the linkage plate, a cleaning brush is fixedly connected to the right side of the movable plate, and a slider is fixedly connected to the top of the movable plate. The slider is slidably connected to the top of the fixed block. When the movable plate drives the cleaning brush to move, the movable plate can drive the slider to move. The slider can limit the movable plate, so that when the rack plate moves outside the limiting rod, the rack plate is not easy to rotate left and right, making the rack plate more stable during the movement.

[0009] According to the above technical solution, a first spring is sleeved around the limiting rod. The front of the first spring is fixedly connected to the back end of the rack plate, and the side of the first spring away from the rack plate is fixedly connected to the front of the short plate. When the gear drives the rack plate to move, the rack plate can squeeze the first spring. When the gear stops rotating, the first spring can drive the rack plate to return to its original position, so that the rack plate can drive the moving plate to return to its original position through the linkage plate, so that the cleaning brush can reciprocate to clean the filter plate, making the filter plate less prone to clogging.

[0010] According to the above technical solution, the filtering mechanism includes a filter plate, which is slidably connected to the inside of a fixed block. Baffles are fixedly connected to the front and rear sides of the filter plate. A connecting plate is fixedly connected to the bottom of the baffles. A pressing block is fixedly connected to the back end of the connecting plate. A limiting block is provided at the top of the pressing block. The bottom of the limiting block and the top of the pressing block are in contact with each other. A pull rod is fixedly connected to the back end of the limiting block. The pull rod is slidably connected to the inside of the fixed block. A limiting plate is fixedly connected to the side of the pull rod away from the limiting block.

[0011] According to the above technical solution, a second spring is sleeved around the pull rod. The back end of the second spring is fixedly connected to the inside of the fixing block, and the side of the second spring away from the fixing block is fixedly connected to the back end of the limiting block. When the filter plate is fixed, the filter plate is inserted into the fixing block, so that the filter plate can drive the connecting plate to move through the baffle plate, so that the connecting plate can drive the pressing block to squeeze the limiting block, so that the pressing block can squeeze the second spring. When the limiting block is not squeezed by the pressing block, the second spring can drive the limiting block to return to its original position, so that the limiting block can limit the pressing block, making it less likely for the filter plate to shake and fall off during use.

[0012] According to the above technical solution, the transmission mechanism includes a fixed pipe, which is fixedly connected to the inside of the denitrification cylinder. A transmission rod is rotatably connected inside the fixed pipe. A plate compressor is fixedly connected to the right side of the transmission rod. A worm gear blade is fixedly connected to the side of the transmission rod away from the compressor. The fixed pipe is fixedly connected to the right side of the fixed block. A filter screen is fixedly connected to the right side of the fixed pipe.

[0013] According to the above technical solution, a diversion cylinder is fixedly connected to the bottom of the fixed pipe, and an air outlet is opened on the periphery of the diversion cylinder. The industrial waste gas that needs to be denitrified can be transmitted to the inside of the diversion cylinder through the worm gear blades. The industrial waste gas can be diverted through the diversion cylinder, so that the diverted industrial waste gas can be neutralized by the neutralizing solution, so that the industrial waste gas can meet the emission standards.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: This turbocharged negative pressure desulfurization and denitrification equipment uses a motor on the cleaning mechanism to drive a worm gear, which in turn drives a transmission worm wheel. The transmission worm wheel then drives a gear via a rotating rod, which in turn drives a rack plate. The rack plate, in turn, drives a moving plate via a linkage plate. This moving plate, along with a cleaning brush, cleans the filter plate, enabling the filter plate to filter the gas. A slider limits the movement of the moving plate, making it more stable during movement.

[0015] This turbocharged negative pressure desulfurization and denitrification equipment filters gas through a filter plate on the filtration mechanism, preventing particulate matter from remaining inside the denitrification cylinder. The baffles connected to the front and rear sides of the filter plate move the connecting plate, allowing the connecting plate to press against the limiting block via a pressing block. This limiting block, in turn, presses against the first spring. When the pressing block stops pressing against the limiting block, the first spring moves the limiting block, preventing it from shaking or falling off during use and ensuring a more secure filter plate.

[0016] This turbocharged negative pressure desulfurization and denitrification equipment uses a compressor in the rising box via a transmission mechanism to draw in air from the outside of the denitrification cylinder. The high-speed airflow drives the worm gear blades to rotate via a transmission rod, allowing the worm gear blades to draw in the gas that needs to be desulfurized and denitrified. The gas is then neutralized by chemicals placed inside the denitrification cylinder, and a filter screen blocks impurities in the air, preventing them from damaging the compressor.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides the following technical solutions: Example 1

[0021] Combination Figure 1-6 A turbocharged negative pressure desulfurization and denitrification device includes a denitrification cylinder 5, a support plate 2 fixedly connected to the left side of the denitrification cylinder 5, a fixing block 3 fixedly connected to the top of the support plate 2, a filter mechanism 4 fixedly connected inside the fixing block 3, a cleaning mechanism 6 fixedly connected to the bottom of the fixing block 3, a transmission mechanism 7 fixedly connected inside the denitrification cylinder 5, and a chemical inlet pipe 1 fixedly connected to the front of the denitrification cylinder 5. The cleaning mechanism 6 includes a motor 65, which is fixedly connected to the top of the support plate 2. A worm gear 604 is fixedly connected to the back end of the motor 65. A transmission worm wheel 606 is meshed at the bottom of the worm gear 604. A rotating rod 602 is fixedly connected inside the transmission worm wheel 606. Arc-shaped plates 63 are fixedly connected to the left and right sides of the rotating rod 602. Arc-shaped plates 63 are fixedly connected to the top of the support plate 2. An air inlet pipe 62 is fixedly connected to the left side of the fixing block 3.

[0022] Furthermore, a gear 603 is fixedly connected to the side of the rotating rod 602 away from the transmission worm gear 606. A rack plate 605 meshes with the top of the gear 603. A limit rod 66 is slidably connected inside the rack plate 605. A short plate 64 is fixedly connected to the front and back ends of the limit rod 66. The short plate 64 is fixedly connected to the top of the support plate 2. When the worm 604 drives the transmission worm gear 606 to rotate, the transmission worm gear 606 can drive the gear 603 to rotate through the rotating rod 602. This allows the gear 603 to drive the moving plate 68 to move through the rack plate 605 and the linkage plate 67. The moving plate 68 can then clean the filter plate 47 through the cleaning brush 69, making the filter plate 47 less prone to clogging.

[0023] Furthermore, a linkage plate 67 is fixedly connected to the left side of the rack plate 605, a movable plate 68 is fixedly connected to the left side of the linkage plate 67, a cleaning brush 69 is fixedly connected to the right side of the movable plate 68, and a slider 601 is fixedly connected to the top of the movable plate 68. The slider 601 is slidably connected to the top of the fixed block 3. When the movable plate 68 drives the cleaning brush 69 to move, the movable plate 68 can drive the slider 601 to move. The slider 601 can limit the movable plate 68, so that when the rack plate 605 moves around the limit rod 66, the rack plate 605 is not easy to rotate left and right, making the rack plate 605 more stable during the movement.

[0024] Furthermore, a first spring 42 is sleeved around the limiting rod 66. The front of the first spring 42 is fixedly connected to the back end of the rack plate 605, and the side of the first spring 42 away from the rack plate 605 is fixedly connected to the front of the short plate 64. When the gear 603 drives the rack plate 605 to move, the rack plate 605 can squeeze the first spring 42. When the gear 603 stops rotating, the first spring 42 can drive the rack plate 605 to return to its original position, so that the rack plate 605 can drive the moving plate 68 to return to its original position through the linkage plate 67, so that the cleaning brush 69 can reciprocate to clean the filter plate 47, making the filter plate 47 less prone to clogging. Example 2

[0025] See Figure 1-6 Furthermore, based on Embodiment 1, the filter mechanism 4 further includes a filter plate 47, which is slidably connected to the inside of the fixed block 3. Baffle plates 48 are fixedly connected to the front and rear sides of the filter plate 47. A connecting plate 46 is fixedly connected to the bottom of the baffle plate 48. A pressing block 41 is fixedly connected to the back end of the connecting plate 46. A limiting block 45 is provided at the top of the pressing block 41. The bottom of the limiting block 45 is in contact with the top of the pressing block 41. A pull rod 43 is fixedly connected to the back end of the limiting block 45. The pull rod 43 is slidably connected to the inside of the fixed block 3. A limiting plate 44 is fixedly connected to the side of the pull rod 43 away from the limiting block 45.

[0026] Furthermore, a second spring 61 is sleeved around the pull rod 43. The back end of the second spring 61 is fixedly connected to the inside of the fixing block 3, and the side of the second spring 61 away from the fixing block 3 is fixedly connected to the back end of the limiting block 45. When the filter plate 47 is fixed, the filter plate 47 is inserted into the fixing block 3, so that the filter plate 47 can drive the connecting plate 46 to move through the baffle plate 48. The connecting plate 46 can drive the pressing block 41 to press the limiting block 45, so that the pressing block 41 can press the second spring 61. When the limiting block 45 is not pressed by the pressing block 41, the second spring 61 can drive the limiting block 45 to return to its original position, so that the limiting block 45 can limit the pressing block 41, making it less likely for the filter plate 47 to shake and fall off during use. Example 3

[0027] See Figure 1-6 Furthermore, based on Embodiment 1, the transmission mechanism 7 further includes a fixed pipe 77, which is fixedly connected to the inside of the denitrification cylinder 5. A transmission rod 74 is rotatably connected inside the fixed pipe 77. A compressor 73 is fixedly connected to the right side of the transmission rod 74 via a plate 46. A worm gear blade 76 is fixedly connected to the side of the transmission rod 74 away from the compressor 73. The fixed pipe 77 is fixedly connected to the right side of the fixed block 3. A filter screen 72 is fixedly connected to the right side of the fixed pipe 77.

[0028] Furthermore, a diversion cylinder 71 is fixedly connected to the bottom of the fixed pipe 77, and an air outlet 75 is opened on the periphery of the diversion cylinder 71. The industrial waste gas that needs to be denitrified can be transmitted to the inside of the diversion cylinder 71 through the worm gear blades 76. The industrial waste gas can be diverted through the diversion cylinder 71, so that the diverted industrial waste gas can be neutralized by the neutralizing solution, so that the industrial waste gas can meet the emission standards.

[0029] In actual operation, when this device is in use, the filter plate 47 is inserted into the fixed block 3, so that the connecting plate 46 can press the limiting block 45 through the pressing block 41, so that the limiting block 45 can drive the first spring 42 to press. When the pressing block 41 does not press the limiting block 45, the first spring 42 can drive the limiting block 45 to move, so that the limiting block 45 can block the pressing block 41. The chemical solution for neutralizing industrial waste gas can be introduced into the denitrification cylinder 5 through the chemical inlet pipe 1. When industrial waste gas needs to be absorbed, compressor 73 is turned on to absorb the gas. Rotating rod 602 drives worm gear blades 76 to rotate, allowing them to absorb the industrial waste gas. The waste gas is then transported through fixed pipe 77 to the distribution cylinder 71, where neutralizing solution neutralizes it, ensuring it meets emission standards. When filter plate 47 is blocked by particulate matter inside the waste gas, motor 65 is turned on to allow the gas to pass through... The worm gear 604 drives the transmission worm wheel to rotate, which in turn drives the gear 603 to rotate via the rotating rod 602. The gear 603 then drives the linkage plate 67 to move via the rack plate 605. This causes the rack plate 605 to compress the first spring 42, which in turn causes the linkage plate 67 to move the moving plate 68. The moving plate 68 then drives the cleaning brush 69 to clean the filter plate 47. When the motor 65 stops rotating, the first spring 42 returns to its original position via the rack plate 605, causing the rack plate 605 to... 05 can drive the moving plate 68 to return to its original position through the linkage plate 67, so that the moving plate 68 can drive the cleaning brush 69 to brush the filter plate 47, and the moving plate 68 can drive the cleaning brush 69 to clean the filter plate 47 back and forth. When the filter plate 47 is severely blocked, the limit plate 44 is pulled, so that the limit plate 44 can drive the limit block 45 to move through the pull rod 43, so that the limit block 45 can move away from the pressing block 41, and the filter plate 47 can be easily disassembled and cleaned by the staff.
